+peer --> relay: Establish connection
+
+ps -> redis: PUSH message on \n(msgbus.system.local)
+redis -> peer : POP message from \n(msgbus.system.local)
+
+peer -> relay: message pushed over the websocket to the relay
+...
+relay -> peer: received response
+peer -> redis: PUSH over $msg.reply_to queue
+...
+note across: Handling In Request
+relay --> peer: Received a request
+peer -> redis: PUSh request to `msgbus.$cmd`
